虽然 WebService 这个框架已经过时，但是有些公司还在使用，在调用他们的服务的时候就不得不面对各种问题，本篇文章总结了最近我调用他司 WebService 的心路历程。3 种方式可以分别尝试，哪种能通用哪个。
1. HttpClient
依赖：
<!-- lombok -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
<!-- Apache Http httpclient_version-->
<dependency>
<groupId>org.apache.httpcomponents.client5</groupId>
<artifactId>httpclient5</artifactId>
<version>5.1.3</version>
</dependency>
代码：
import lombok.extern.slf4j.Slf4j;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.HttpEntity;
@Slf4j
public class HttpClientUtil {
/**
* HttpClient 调用 WebService
* @param wsUrl webService地址，格式：http://ip:port/xxx/xxx/soap?wsdl
* @param json格式的入参
* @return
*/
public static String callServiceHC(String wsUrl, String jsonStr) {
String xml = createSoapContent(jsonStr);
String returnDatabase = doPostSoap(wsUrl, xml, "");
log.info("returnDatabase===>{}", returnDatabase);
return returnDatabase;
}
/**
* 根据拼接 xml 字符串
* @param input
* @return
*/
public static String createSoapContent(String jsonStr) {
log.info("开始拼接请求报文");
//开始拼接请求报文
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:zys=\"http://www.chenjy.com.cn/\">\n");
stringBuilder.append("<soapenv:Header/>\n");
stringBuilder.append("<soapenv:Body>\n");
stringBuilder.append("<cjy:CallInterface>\n");
stringBuilder.append("<cjy:msgHeader><![CDATA[\n");
stringBuilder.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");
stringBuilder.append("<root>\n");
stringBuilder.append("<serverName>getInfo</serverName>\n");
stringBuilder.append("<format>xml</format>\n");
stringBuilder.append("<callOperator>测试</callOperator>\n");
stringBuilder.append("<certificate>AcsaoP21Lxw5KAoQu6SLs624bhGjwNL0DzxsQ9a7B/HbqNsPPcA==</certificate>\n");
stringBuilder.append("</root>\n");
stringBuilder.append("]]></cjy:msgHeader>\n");
stringBuilder.append("<cjy:msgBody><![CDATA[\n");
stringBuilder.append( jsonStr+ "\n");
stringBuilder.append("]]></cjy:msgBody>\n");
stringBuilder.append("</cjy:CallInterface>\n");
stringBuilder.append("</soapenv:Body>\n");
stringBuilder.append("</soapenv:Envelope>");
log.info("拼接后的参数"+stringBuilder.toString());
return stringBuilder.toString();
}
/**
* HTTPClient 调用 WebService
* @param url
* @param soap
* @param SOAPAction
* @return
*/
public static String doPostSoap(String url, String soap, String SOAPAction) {
//请求体
String retStr = "";
// 创建HttpClientBuilder
HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
// HttpClient
CloseableHttpClient closeableHttpClient = httpClientBuilder.build();
HttpPost httpPost = new HttpPost(url);
try {
httpPost.setHeader("Content-Type", "text/xml;charset=UTF-8");
httpPost.setHeader("SOAPAction", SOAPAction);
StringEntity data = new StringEntity(soap,
Charset.forName("UTF-8"));
httpPost.setEntity(data);
CloseableHttpResponse response = closeableHttpClient
.execute(httpPost);
HttpEntity httpEntity = response.getEntity();
if (httpEntity != null) {
// 打印响应内容
retStr = EntityUtils.toString(httpEntity, "UTF-8");
}
// 释放资源
closeableHttpClient.close();
} catch (Exception e) {
e.printStackTrace();
}
return retStr;
}
}
注意：拼接 xml 字符串的时候要根据实际的 WebService 地址拼接，可在 soapui 中导入 wsurl 获取到入参，如下：
把这些参数全部拼接进去：
2. Http post
依赖：
<!-- lombok -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
<!-- jodd-http -->
<dependency>
<groupId>org.jodd</groupId>
<artifactId>jodd-http</artifactId>
<version>6.3.0</version>
</dependency>
代码：
import lombok.extern.slf4j.Slf4j;
import jodd.http.*;
public class HttpPostUtil {
/**
* http post 调用 WebService
* @param wsUrl
* @param jsonStr
* @return
*/
public static String callServiceHP(String wsUrl, String jsonStr) {
String xml = createSoapContent(jsonStr);
String uploadFeeDetailJsonStr = postWs(wsUrl, xml);
return uploadFeeDetailJsonStr;
}
/**
* 根据拼接 xml 字符串
* @param input
* @return
*/
public static String createSoapContent(String jsonStr) {
log.info("开始拼接请求报文");
//开始拼接请求报文
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:zys=\"http://www.chenjy.com.cn/\">\n");
stringBuilder.append("<soapenv:Header/>\n");
stringBuilder.append("<soapenv:Body>\n");
stringBuilder.append("<cjy:CallInterface>\n");
stringBuilder.append("<cjy:msgHeader><![CDATA[\n");
stringBuilder.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");
stringBuilder.append("<root>\n");
stringBuilder.append("<serverName>getInfo</serverName>\n");
stringBuilder.append("<format>xml</format>\n");
stringBuilder.append("<callOperator>测试</callOperator>\n");
stringBuilder.append("<certificate>AcsaoP21Lxw5KAoQu6SLs624bhGjwNL0DzxsQ9a7B/HbqNsPPcA==</certificate>\n");
stringBuilder.append("</root>\n");
stringBuilder.append("]]></cjy:msgHeader>\n");
stringBuilder.append("<cjy:msgBody><![CDATA[\n");
stringBuilder.append( jsonStr+ "\n");
stringBuilder.append("]]></cjy:msgBody>\n");
stringBuilder.append("</cjy:CallInterface>\n");
stringBuilder.append("</soapenv:Body>\n");
stringBuilder.append("</soapenv:Envelope>");
log.info("拼接后的参数"+stringBuilder.toString());
return stringBuilder.toString();
}
/**
* 调用 webService
* @param url
* @param jsonStr
* @return
*/
public static String postWs(String url, String jsonStr) {
HttpResponse resp = HttpRequest.post(url).connectionTimeout(60000).timeout(60000)
.contentType("application/xml", StandardCharsets.UTF_8.toString())
.header("SOAPAction","")
.bodyText(jsonStr, "application/xml", "utf-8")
.charset(StandardCharsets.UTF_8.toString()).trustAllCerts(true)
.send();
resp.charset(StandardCharsets.UTF_8.toString());
return resp.bodyText();
}
}
3. cxf
因为我用 cxf 调不通，所以就在这里就直接奉上其他博主的调用案例：
